Inexpensive Multi-Touch Pressure Acquisition Devices (IMPAD) are flexible, paperthin sensing surfaces that can scale from portable devices to large tables. These devices can sense varying levels of pressure at a resolution high enough to sense and distinguish multiple fingertips, the tip of a pen or pencil and other objects. Other potential applications include writing pads, floor mats and entr...

-A hardware and software design and development is described for a two-channel portable recording device specifically to collect the electroencephalogram (EEG). The application intended for this device was collection of EEG data from drivers, while driving under controlled conditions on closed roads or circuits. The monitoring of driver reactions may lead to a better understanding of driving ab...

Portability of equipment is an increasingly important component in the practice of audiology. We report on a new device, the OtoID, that supports evidence-based ototoxicity testing protocols, provides capability for hearing testing on the hospital treatment unit, and can automate patient self-testing. The purpose of this article is to report on the validation and verification of the OtoID porta...

BACKGROUND The exhaled nitric oxide (FeNO) is a non-invasive marker of airway inflammation in asthma. A very recent statement has suggested FeNO as potential outcome in chronic obstructive pulmonary disease (COPD). Recently, a new hand-held FeNO analyzer (NIOX MINO) has been developed. PATIENTS AND METHODS We have evaluated the NIOX MINO in COPD patients and monitored FeNO levels during 1-yea...

The increase in the prevalence of chronic respiratory diseases has resulted in a rise in health services provided at home. The forced oscillation technique (FOT) proves to be a useful tool when it is desired to assess lung function noninvasively, and particularly for patients in whom spirometry cannot be applied. As no portable FOT device is currently available, the aim of this study was to des...

A PIC17C44 microcontroller development board and a real-time algorithm were developed with the capability of monitoring the fetal heart rate (FHR) as well as recording both the FHR and maternal heart rate for long-term. This paper describes the development of the microcontroller board and implementation of a real-time algorithm which were used to develop the portable recorder. Two set-up were d...

Workstation/PC clusters have become a cost-effective solution for high performance computing. C-DAC’s PARAM 10000 (or OpenFrame, internal code name) is a large cluster of high-performance workstations interconnected through low-latency and high bandwidth networks. The management and control of such a huge system is a tedious and challenging task since workstations/PCs are typically designed to ...

New challenging deployment scenarios are accommodating portable devices with limited and heterogeneous capabilities that roam among wireless access localities during service provisioning. That calls for novel middlewares to support different forms of mobility and connectivity in wired-wireless integrated networks, to provide runtime service personalization based on client characteristics, prefe...

A portable diffuse correlation spectroscopy (DCS) flowmeter has been extended to measure both tissue blood flow and oxygenation (namely, DCS flow oximeter). For validation purposes, calf muscle blood oxygenation during cuff inflation and deflation was measured concurrently using the DCS flow oximeter and a commercial tissue oximeter. The oxygenation traces from the two measurements exhibited si...
